title: Radiologic assessment of retropharyngeal node involvement in oropharyngeal carcinomas stratified by HPV status.
abstract: Radiation of retropharyngeal nodes (RPN) results in increased toxicities. This study assessed characteristics associated with RPN involvement in 165 oropharynx cancer patients. Factors associated with involvement were stage N2c-3 disease and stage N2b disease with either advanced T-stage, ⩾3 involved cervical LN, and ⩾1 involved contralateral LN, or lateral/posterior subsites.
